Why it works: Peas and mint are a kitchen classic. They rank in the top 2% of all ingredient pairs, and 1,137 recipes mention both. Both carry 1-octen-3-ol, which smells mushroom, earthy. The science ↓
To Make a Fine Pease Soup
Ingredients
Directions
Cook the peas
Tie the peas in a cloth, allowing room to swell, and place them in a pan of cold water.
Place a common plate in the pan to keep the cloth off the bottom.
Bring the water to a boil and let the peas cook for 1 hour.
In the meantime, bring the soup to a boil.
Remove the peas from the cloth.
Make the soup
Bruise the peas well.
Mix the bruised peas with a ladleful of soup, then add more soup gradually until the mixture is combined.
Return the mixture to the pan.
Add the grated carrot, minced onion, spinach, sliced potatoes, and bacon if using.
Let it all boil together for 30 minutes.
Season with salt and pepper to taste.
Strain and serve
Strain through a fine sieve, working the pea pulp through with a wooden spoon.
Return the strained soup to the pan, bring to a boil, and serve.
If desired, add a little dried mint for flavor.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried peas
- Break down when bruised and strained to thicken the soup and give it body.
- Potatoes
- Break down during simmering to add starch and thicken the soup further.
- Onion
- Adds aromatic sweetness and savory depth as it softens in the soup.
- Carrot
- Adds natural sweetness and color to the soup.
The step that matters
Straining the pea pulp. Working the bruised peas through a fine sieve pushes the softened pulp through while leaving skins behind, which gives the soup a smooth texture. Skipping or rushing this leaves the soup grainy.
Flavor stand-ins for the mint
The recipe marks mint as optional. How well each one fits the dish's main ingredients (peas, carrot, onion, spinach, potato, pepper):
- Parsleybetter flavor fit
- Cuminbetter flavor fit
- Garlicbetter flavor fit
- Mintthe original
Fit is the average pairing score against peas, carrot, onion, spinach, potato, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
